Title: Daryl Chapman: Innovator in Fuel Cell Technology
Introduction
Daryl Chapman is a notable inventor based in Victor, NY (US). He has made significant contributions to the field of fuel cell technology, holding a total of 5 patents. His work focuses on enhancing the efficiency and safety of hydrogen-powered fuel cells.
Latest Patents
One of Daryl's latest patents is the "Non-flammable exhaust enabler for hydrogen powered fuel cells." This innovative fuel cell system employs a purge valve, an accumulator, and a bleed valve for selectively purging and bleeding anode exhaust gas. When the purge valve is opened, the anode exhaust gas purges to the accumulator where it is collected. The bleed valve provides a controlled release of the anode exhaust gas from the accumulator, allowing the concentration of hydrogen bled from the accumulator to remain below its combustible limit. In one embodiment, the purged anode exhaust gas is combined with the cathode exhaust gas and released to the atmosphere. In another embodiment, the purged anode exhaust gas is combined with a cathode input gas. Additionally, in another embodiment, the purged anode exhaust gas is combined with an anode input gas.
Another significant patent is the "Current control for parallel fuel cell stacks." This system includes fuel cell stacks that are electrically connected in parallel and supply a gross current to a load. A controller determines the gross load current and produces a desired current through the load by adjusting, based on the gross load current, at least one parameter affecting at least one of the inputs to and outputs from the system. This design allows for a constant stack design and voltage output while adding stacks for increased power.
